摘要： A radio communication method acquires a moving speed of a radio communication terminal located in a cell formed by a first radio base station. A second radio base station is requested to radiate a dynamic directional beam in a direction of the cell formed by the first radio base station when the moving speed is equal to or more than a predetermined threshold prior to entering a cell formed by the second radio base station. The radio communication terminal is accommodated in the second radio base station that has transmitted the directional beam in response to the request.

摘要： A radio base station includes: a propagation path characteristic acquisition unit which acquires propagation path characteristics between a radio communication terminal and a radio base station; and a channel controller which reports to the radio communication terminal that channel allocation information is transmitted by using a dedicated control channel if the acquired propagation characteristic satisfies a predetermined condition. After the channel control unit has reported to the radio communication terminal that the channel allocation information is transmitted by using an dedicated control channel, the channel control unit and a MAP processing unit transmit the channel allocation information by using an dedicated control channel instead of a broadcast control channel in the downstream frame.
